if user A in one domain is able to call user B in another domain, i
don't understand why it is not tolerable that user A sends a REFER to
user B.
Imagine user_B uses a Linksys or any other deskphone (most of them allow
incoming REFER without asking permission to the user).
- user_B@domain_B calls to PSTN number of domain_A.
- Our OpenSer via ENUM query determines the target is user_A@domain_A.
- The call is established.
- Now user_A@domain_A sends a REFER with "Refer-to: 004598623435@domain_B".
- user_B@domain_B phone is automatically referred to an internacional PSTN
number via our OpenSer with no knowledge of user_B.
- The international call is answered and tarified to domain_B account.
I do see a problem.
